The following excerpt is from John Gill concerning the eternal Sonship of Christ.
“The incarnation of Christ is not the reason of his being the Son of God, but the manifestation of him as such; he was not made, but manifested thereby to be the Son of God (1 John 1:12, 3:8). In the fulness of time God sent forth his Son—for what? not to be made a Son; he was so before he sent him; but that this Son might be made of a woman, or be made man; that the Word might be made flesh, or become incarnate; and so God, the Son of God, be manifest in the flesh (Gal. 4:4).” -John Gill, Body of Doctrinal Divinity, Book 2, Chapter 28, Section 6b3d4
John Gill’s section on the eternal Sonship of Christ is one of the best written on the subject. It gives a thorough defense from both a biblical and philosophical perspective. It likewise answers many objections from those that deny the eternal Sonship of Christ.
